Tolall whom it may concern:

'Be it known that I, MARC K. MERMQD a citizen of the Republic of Switzerland, re-

siding at New York citycounty and State of New York, have invented certain newV and useful Improvements in Fluid-Distributing Apparatus, of which the following is a full, clear, andexact description.

lVIy invention relates to apparatus for the distribution of fluid, and particularly liquid soap.

The object of the invention is to provide an improved construction for the manual control anda distribution of fluids in quantities as desired.

The invention comprises broadly a fluid supply reservoir, an outlet and a manually operable plunger which controls the feed of the fluid from said reservoir to said outlet.

Preferred embodiments of my invention are illustrated in the accompanying drawings, in which,

Figure Ll is a vertical sectional view of the device embodying myinvention; Fig. 2 .is an end view of the plunger shown in Fig. l; Fig. 3 is a view similar to Fig. 1 of a modified form of my' invention; F ig. 4 is an end view of the plunger shown in Fig. 3; Fig. 5 .is a view similar to Figs. 1 and 3 of a further modiiication; Fig. 6 is a transverse sectional view on the line 6 6 of the plunger shown in Fig. 5; Fig. 7 is a view of the plunger shown in Fig. 5 detached; Fig. 8 is a transverse sectional view of the plunger sho wn in Fig. 5 on the line '8 8 of said figure; Fig. 9 is a 'view similar to Fig. 1 ofa further modification; Fio. 10 is a transverse sectional view on the line 10-10 of the plunger shown in Fig. 9; and, Fig. 11 is a transverse sectional view on the line 11-11 of said plunger.

In the embodiment of my invention illustratedin Figs. l and 2, the device comprises a reservoir 1 preferably made of glass, a plunger cylinder 2 which is provided. with a base 3, by which the device may be secured to the wall adjacent a xture such as a wash basin or the like. The cylinder 2 is provided with a boss 2 which is threaded to receive a threaded tubular portion 4 of the reservoir,

' .by which the latter is attached to said cylinder. On the lower side of said cylinder,

preferably opposite the point of attachment of the reservoir, is an" outlet 5. Within the cylinder 2 is mounted a plunger 6 recessed at 7 at its inner end to provide a fluid receiving chamber and having a small bore 8 communicating with said chamber for a pur? pose hereinafter to be described. Interposed between the plunger 6 and the base 3 is a spring 9, which normally holds the plunger in projected position. A stop pin 10 fixed to the cylinder 2 and workingjwithin a slot 11 of the plunger determines the eX- tent of movement of the latter. In the wall of the cylinder 2 and opposite the tubular outlet' l of the reservoir is an aperture or passage12, which, when the plunger moves inward and outward, is adapted to register momentarily with a like aperture 13 Ain the wall of the recess 7 in saidplunger. Also at the lower side of said plunger in the wall of the recess thereof is a second aperture or passage 14, which, when the plunger is moved to the full extent of its inward stroke, registers with the outlet 5. In the operation of the device, the. reservoir is filled with the desired liquid,"such, for example, as liquid soap, The plunger is then pushed inwardly, and while returning under the iniiuence of spring 9 and when the aperture 13 'registers with the passage l2 in the cylinder' wall on.

the return stroke, the desired quantity of fluid will be drawn into the chamber 7 of the plunger, due to the suction caused by the partial vacuum produced in Achamber 7 by the outward movement of the plunger and to the' after the'chamber 7 has been charged with fluid, as above described, the fluid in said chamber will be more or less forcibly eJected out through said outlet 5 by reason of the compression of the air and uid in the chami ber formed wit-hin the. plunger and also within the cylinder 2. Repeated pressures upon theplunger will serve to charge the chamber 7 and eject the corresponding quantities of the fluid as desired. The auxiliary chamber for-med by the bore 8 in the plunger aford's space for the compressed air within the chamber 7, and being above' the bottom of said chamber, there will be no tendency i advance of'the passage 19 when the plunthe chamber 16 withinfthe p of such compressed air to escape through the outlet 5, thus interfering with the proper ejection of the fluid. r

It will be noted vfrom the above description. that when the plunger is atrest in its projected position, the passage from the liquid reservoir to the chamber 7 is effectually closed, thereby preventing leakage at this point, andr also the passage from the chamber 7 to the outlet 5 is likewise eiectually closed, whereby all leakage is prevented here also. l

- In the modified form of my invention illustrated in Fig. 3, the parts 1, 2, 2', 3, 4 and 5 correspond in construction to the parts similarly indicated in Fig. 1. The construction of the plunger in this form, however, is somewhat modified, -and comprises preferably the body portion 15 having a recess orA chamber 16 formed therein either by drilling at the center, or by a transverse kerf, as indicated in Fig. 4. A spring 17 is interposed between the rear end of the plunger andl the base 3. This plunger is also provided with an auxiliary chamber or bore 18 corresponding to the chamber 8 in Fig. 1.

The wall of the cylinder 2 also is provided with a passage19 corresponding to the passage 12 in Fig. 1,'and the plunger 15 is provided with a passage 20 which lies just'in er is in projected position. Also at the ower side of the plunger is a passage 21 adapted to registerwith the outlet- 5 when the plunger 1s in its innermost position.

Movement of this plunger also is limited by the pin 22 working in the slot 23.

j The (peration of the construction just describe is substantially similar to that heretofore stated, but the ta ering form .of fiinger serves to concentrate the fluid rather moreefectually at a oint opposite the outlet passage 21, where y the liquid is'lnore effectually ejected through the outlet 5. v

In the modified form of the invention illustrated` in Fig. 5, the parts 1,2, 2, 3 and 4 and 5 correspond to parts similarly indicated in Fig. 1. In this orm ofthe invention,

however, the plunger, when moved inwardly, l

is given a simultaneous rotary movement to lbring the various inlet and outlet passages in proper register. With this end 1n view, the `cylinder is provided with the aperture 24 communicating with the reservoir 1.; and the plunger 25 is provided with a'chamber 26 in the wall of which is formed an inlet passage or aperture 27, which,when the plunger is lin normal projected position, is in advanceof the a erture 24 and is slightly displaced angu arly with respect thereto. Likewise, the plun er is provlded with an outlet aperture 28 a aipted to aline With the outlet 5 when the plunger is moved Y tof its extreme inward position, and which is also normally angularly displaced with respect to said outlet 5. The body of the plunger furthermore is provided with a spiral groove or slot`29, which engages a pin 30 projecting from the inner wallv ofthe cylinder 2, whereby, when the plunger moves inward and outward, it will begiven a rotative movement which will bringl the aperture 27 in alinement with the aperture 24, communicating with the reservoir; and, upon further inward movement,'will bring the aperture 28 into alinement with the outlet 5. In other respects the operation of this form of the invention is the same as that heretofore described.

` In the form illustrated in Fig. 9, the parts 1, 2, 2', 3, 4, and 5 correspond to the parts similarly indicated in Fi 1. In this case,

as in the fprm illustrated 1n Fig. 5, the lunger is given a rotative movement to ring lts varlous passages Vinto communication with the reservoir and the outlet. In this construction, however, such. rotative movement is effected by means of va screw stem 31, which engages a corresponding screwthread 32 within the plunger and the outer end of the plunger is provided with a stem 33 having a cross-head or handle 34 for manual operation. In this form also, as in the form illustrated in Fig. 5, the cylinder is provided with a passage 35 communicating with the reservoir 1 and the plunger 1s provided with a passage 36, which, when the plunger -is in normal position, is slightly in advance of the passage 35 and is angularly displaced with respect thereto. Such cylinder also, is provided with an outlet passage 37 to afford communication with the outlet 5 and Which,-when` the plunger is in normal position, is likewise angularly Idisplaced with respect to said outlet 5. The plunger may be manually rotated to bring the pas- Sages 36 and 37' into alinement with the passage 35 and outlet 5 respectively to charge and discharge the plunger chamber as above described.

In all forms of the invention above described it will` be seen that when the plunger is in' normal projected lposition all communication between the suppl reservoir 'and the cylinder, and between e cylinder of the outlet, is etfectually closed, thus preventing any possibility of leakage.
